CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY

This application claims the benefit of Korean Patent Application No. 10-2015-0100401, filed on Jul. 15, 2015 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

TECHNICAL FIELD

Embodiments of the present disclosure relate to a dehumidifier which is used to decrease indoor humidity.

BACKGROUND

Generally, a dehumidifier is a device which removes moisture in the air. The dehumidifier may be largely divided into a dry type and a cooling type. The dry type performs dehumidification by absorbing or adsorbing moisture in the air using a moisture absorbent material which is a chemical, while the cooling type condenses vapor in the air by cooling the air to the dew point or below using a refrigeration cycle apparatus.

In the cooling type dehumidifier, a temperature of air near a cooling apparatus is decreased to the dew point or below, accordingly, a condensation water is generated in the cooling apparatus, and a water container which stores the condensation water which falls from the cooling apparatus is provided under the cooling apparatus.

When the water container is full with water or during a removal of the water container, when the water container of the dehumidifier is shaken, water may flow at a water collecting structure, specifically, at a portion where the water container is mounted.

Conventionally, a water container and a water collecting structure which store condensation water of a dehumidifier are positioned at a lower portion of the dehumidifier a concave bucket is formed to collect water at a position where water drops when the water container is removed.

Accordingly, when water is collected in the bucket, a user needs to wait until the water is evaporated or wipe the bucket. In addition, when the dehumidifier is carried without removing water, the water may be leak out of the product.

The main body 110 of the dehumidifier 100 may include a main case 111 having an accommodation space accommodating various components and a bottom case 113 coupled to a lower portion of the main case 111. The inlet port 115 of the dehumidifier 100 may be formed at the front of the main body 110, and the outlet port 116 may be formed at an upper portion of the main body 110.

The outlet port 116 may be provided with a grille 116 a for preventing external foreign materials from penetrating into the dehumidifier 100. In addition, the outlet port 116 may be provided with a blade 117 which adjusts a direction of discharged air or opens and closes the outlet port 116. The blade 117 may be provided rotatable about a rotation shaft 117 a.

The refrigeration cycle apparatus including the compressor 120, the condenser 121, the expansion valve, and the evaporator 122 is provided inside the main body 110. The compressor 120 may be disposed at a lower portion of the main body 110, the evaporator 122 may be disposed adjacent to the inlet port 115, and the condenser 121 may be disposed behind the evaporator 122.

The blower fan 125 may be rotated by receiving rotary power from a driving motor 125 a.

In addition, the blower fan 125 may move air by suctioning the air from the front of the main body 110 to sequentially flow the air through the evaporator 122 and the condenser 121 and discharging the air to an upper front side of the main body 110.

An air flow guide 126 for guiding an air flow direction may be provided inside the main body 110.

The blower fan 125 may include a centrifugal fan which suctions air in an axis direction and discharges the air in a radial direction.

The water container mounting portion 140 on which the water container 150 is mounted may be provided in the upper portion of the main body 110. The water container 150 mounted on the water container mounting portion 140 is positioned at a level higher than or at least the same as that of the evaporator 122 or the condenser 121.

The water container mounting portion 140 may include a mounting space 141 in which the water container 150 is mounted, a bottom support portion 142 which supports the lower end of the water container 150, and an outer wall support portion 143 which supports an outer wall 153 of the water container 150.

Water may be collected in the water container mounting portion 140 when a user shakes the water container, when a water level sensor (not shown) which measures a water level in the water container 150 malfunctions, when the water container 150 is separated or mounted, etc. In the above cases, the water may stay in the water container mounting portion 140 or overflow to the outside of the dehumidifier 100.

The water container mounting portion 140 may be provided with the drain hole 170 capable of discharging water to a lower portion thereof toward heat exchangers 121 and 122 when there is the water as described above.

The drain hole 170 may be formed at the bottom support portion 142 of the water container mounting portion 140. In addition, the drain hole 170 may be formed at a position corresponding to upper portions of the heat exchangers 121 and 122 so that water flows to the heat exchangers 121 and 122.

The drain hole 170 may be a path extending from the water container mounting portion 140 toward the heat exchangers 121 and 122. The path may have a shape similar to a protrusion 172 which will be described below according to the embodiment of the present disclosure.

Since water which falls from the drain hole 170 may be evaporated by heat of the condenser 121, the heat exchanger may be the condenser 121.

In addition, since the drain duct 130 which guides water to the water collection tray 131 is provided under the evaporator 122, the heat exchanger may also be the evaporator 122.

Water condensed at the evaporator 122 may flow along the evaporator 122 and fall under the evaporator 122, and water collected in the water container mounting portion 140 may fall onto an upper side of the evaporator 122 or the condenser 121 through the drain hole 170. Here, the drain duct 130 may be provided under the evaporator 122 and the condenser 121 to guide the falling water.

The drain duct 130 may guide water to the water collection tray 131, and to this end, the drain duct 130 may be obliquely provided toward the water collection tray 131. The drain duct 130 may be provided to have a sufficient size to cover overall areas of the evaporator 122 and condenser 121.

The water collection tray 131 may store water. The water collection tray 131 may be provided with a water level sensor (not shown). When water level in the water collection tray 131 reaches the full water level or a predetermined water level, the pump 132 may be driven to pump water stored in the water collection tray 131.

The drain duct 130 and the water collection tray 131 may be separately or integrally formed.

Water pumped by the pump 132 may be guided by the drain pipe 133 to the water container 150 mounted in the upper portion of the main body 110.

As described above, since the water container 150 and the water container mounting portion 140 are provided at an upper portion of the dehumidifier 100 and the drain hole 170 is provided at the water container mounting portion 140 to discharge water to the lower portion thereof, a user may easily separate the water container 150 and empty water, and even when water is spilled in the water container mounting portion 140 during a process of separating or remounting the water container 150, a trouble of the user wiping the spilled water may be saved, and thus convenience may be improved.

In addition, the main body 110 may include a guide 180 protruding upward to guide installation and separation of the water container 150. The guide 180 may protrude upward from the center of the main body 110.

The guide 180 may be inserted into a hollow 157 of the water container 150. The guide 180 may be inserted into the hollow 157 of the water container 150 and support an inner wall 155 of the water container 150.

When mounting the water container 150 on the main body 110, the guide 180 of the main body 110 is inserted into the hollow 157 of the water container 150 as the water container 150 is moved downward from an upper side.

On the contrary, when separating the water container 150 from the main body 110, the guide 180 of the main body 110 is separated from the hollow 157 of the water container 150 as the water container 150 is moved upward from a lower side.

As described above, since the guide 180 is provided to be vertically inserted into the hollow 157 of the water container 150, the water container 150 may be easily mounted and separated. In addition, the water container 150 may be prevented from being unintentionally separated during a process of moving the main body 110 with the water container 150 mounted on the main body 110.

The water container mounting portion 240 may be provided with the drain hole 270 capable of discharging water to a lower portion thereof toward heat exchangers 221 and 222 when the water is collected as described above.

The drain hole 270 may be formed above the heat exchangers 221 and 222 so that water flows to the heat exchangers 221 and 222.

In addition, the drain hole 270 may include a path extending from the water container mounting portion 240 toward the heat exchangers 221 and 222.

Since water which falls from the drain hole 270 may be evaporated by heat of the condenser 221, the heat exchanger may be the condenser 221.

In addition, since the drain duct 230 which guides water to the water collection tray 231 may be provided under the evaporator 222, the heat exchanger may also be the evaporator 222.

The water container mounting portion 240 may be provided with a guide which guides a movement of the water container 250 when the water container 250 is mounted. The water container mounting portion 240 may be provided with a fixing portion which fixes the mounted water container 250. The water container 250 mounted on the water container mounting portion 240 may be positioned at a level higher than or at least the same as that of the evaporator 122.

Water condensed at the evaporator 222 may flow along the evaporator 222 and fall under the evaporator 222, and water collected in the water container mounting portion 240 may fall onto an upper side the evaporator 222 or the condenser 221 through the drain hole 270. Here, the drain duct 230 may be provided under the evaporator 222 and the condenser 221 to guide the falling water.

In the present disclosure, although the drain duct 230 and the water collection tray 231 are separately formed, the drain duct 230 and the water collection tray 231 may be integrally formed.

The drain duct 230 may guide water to the water collection tray 231, and to this end, the drain duct 230 may be obliquely provided toward the water collection tray 231. The drain duct 230 may be provided to have a sufficient size to cover overall areas of the evaporator 222 and the condenser 221.

The water collection tray 231 may store water. The water collection tray 231 may be provided with a water level sensor (not shown). When water level in the water collection tray 231 reaches the full water level, the pump 232 may be driven to pump water stored in the water collection tray 231.

The pump 232 may include a centrifugal pump having a motor (not shown) which generates rotary power and a rotation blade which rotates by receiving the rotary power from the motor. Water pumped by the pump 232 may be guided by the drain pipe 233 to the water container 250 provided at the upper portion of the main body 210.

As described above, since the water container 250 and the water container mounting portion 240 are provided at an upper portion of the dehumidifier 100 and the drain hole 270 is provided at the water container mounting portion 240 to discharge water to the lower portion thereof, a user may easily separate the water container 250 and empty water, and even when water is spilled in the water container mounting portion 240 during a process of separating or remounting the water container 250, a trouble of the user wiping the spilled water therefrom may be saved, and thus, convenience may be improved.

In the embodiment, although the water container 250 has an approximately box shape, it is not limited thereto, and the shape of the water container 250 has no limit.

The water container 250 may be provided with a water level sensor (not shown) which measures a level of water stored in an inner space 254. When water in the inner space 254 of the water container 250 reaches the full water level, an alarm may be set off for an indication to the outside and the operation of the pump 232 may stop.

As is apparent from the above description, when water is collected in a water collecting structure of the dehumidifier, the water is collected in an exterior of a product or is not leaked out of the product according to an aspect of the disclosure.

In addition, user inconvenience for handling water collected in a water container mounting portion of the dehumidifier can be reduced.

While the present disclosure has been described above with reference to the specific embodiments, it may not be limited thereto and it may be understood that various embodiments that may be variously modified or changed by those skilled in the art without departing from the gist as the technical spirit of the present disclosure described in the appended claims may be included in the scope of the present disclosure.
